Abstract

peristaltic pump is disclosed. The peristaltic pump comprises a tube platen; and a plunger (see 3091, figure 277) configured to actuate toward the tube platen (3022). An end of the plunger has a rounded end and a bottom of the tube platen has a generally U shape that provides a radial gap between the plunger and the tube platen about equal to two to three times a wall thickness of an infusion tube. The rounded shapes of the plunger tip and tube platen avoid compressing the walls of the infusion line (3210), thereby reducing the compressive load on the plunger (see also paragraph [00943]).

Claims (26)

What is d is:
1. A pump comprising: a tube platen; and a plunger configured to actuate toward the tube platen, n an end of the plunger has a rounded end and a bottom of the tube platen has a generally U shape that provides a radial gap between the plunger and the tube platen about equal to two to three times a wall ess of an infusion tube.
2. The pump according to claim 1, wherein a minimum distance between the plunger and the tube platen along a path of motion of the plunger is limited by a surface on the tube platen that contacts a portion of the plunger.
3. A pump sing: a tube platen defining a well and a first ting section; and a plunger configured to actuate toward the tube , the plunger having a rounded tip and a second contacting section, wherein the tube platen and the r are configured such that actuation of the plunger toward the tube platen is impeded when the first and second contacting sections contact each other.
4. The pump according to claim 3, wherein the first and second contacting sections are configured to contact each other to leave a predetermined gap between the well of the tube platen and the rounded tip of the plunger.
5. The pump according to claim 4, wherein the predetermined gap is configured to prevent an infusion tube disposed within the tube platen from fully closing.
6. The pump according to claim 4, wherein the predetermined gap is configured to cause an infusion tube disposed within the tube platen to partially occlude fluid flow within the infusion tube.
7. The pump according to claim 4, wherein the predetermined gap is about 0.048 inches.
8. The pump according to claim 4, wherein the ermined gap is about nine percent larger than twice a wall ess of a tube.
9. The pump according to claim 4, wherein the predetermined gap is about two percent larger than twice a wall thickness of a tube.
10. The pump according to claim 4, wherein the predetermined gap is about fifty percent larger than twice a wall thickness of a tube.
11. The pump according to claim 4, wherein the predetermined gap is 8% to 35% larger than twice a wall thickness of an infusion tube.
12. The pump according to claim 3, wherein the first and second contacting sections contact each other such that a gap between the rounded tip and the tube platen is about equal to about eight percent larger than twice a wall thickness of an infusion tube disposed within the tube platen.
13. The pump according to claim 12, wherein the tube platen is configured to receive a ermined range of infusion tube sizes.
14. The pump according to claim 12, wherein the tube platen is configured to receive a ermined infusion tube size.
15. The pump according to claim 12, wherein the rounded tip has a width that is less than an ressed tube er of a tube disposed within the well of the tube platen.
16. A pump comprising: a tube platen defining a well; and a plunger configured to actuate toward the tube platen, the plunger having a rounded wherein the rounded tip has a width that is less than an uncompressed tube diameter of a tube disposed within the well of the tube platen.
17. The pump according to claim 16, wherein the tube platen is configured to receive a predetermined infusion tube size.
18. A pump sing: a tube platen defining a well; and a r configured to e toward the tube platen, the plunger having a rounded wherein the rounded tip has a radius that is less than an uncompressed tube radius of a tube disposed within the well of the tube platen.
19. The pump according to claim 18, n the tube platen is configured to receive a predetermined infusion tube size.
20. The pump according to claim 3, n the first and second contacting sections contact each other such that a gap between the rounded tip and the tube platen is about equal to slightly greater than twice a wall thickness of a tube disposed within the well.
21. The pump according to claim 20, wherein the tube platen is configured to receive a predetermined infusion tube size.
22. A pump comprising: a tube ; and a plunger configured to actuate toward the tube platen, wherein an end of the plunger has a rounded end and a bottom of the tube platen has a generally U shape has a radius of about 0.05 inches.
23. The pump according to claim 22, wherein the rounded end has sides that have an angle between them of 35 degrees.
24. The pump according to claim 22, wherein sides of the rounded end meet a plunger tip radius at a tangent angle.
25. The pump according to claim 22, wherein the plunger has a plunger tip having a length of 0.116 inches.
26. A pump according to any one of claims 1-25, substantially as herein described with reference to the accompanying figures. DEKA PRODUCTS LIMITED RSHIP By their Attorneys HENRY HUGHES IP
